Fig. 3. Correspondence analysis of PLFA patterns of soils spiked with 100 ng/g phenanthrene; c = day 0. The first part of the number describes the volume of methylene chloride used to add phenanthrene to 20 g of soil. The end of the number refers to the number of days after phenanthrene addition that the soil was sampled (i.e., 201 = 20 µL of methylene chloride sampled one day after phenanthrene addition).
